AD5380 Eval Board Schematics

Where are the schematics for the AD5380 IQ Demodulator evaluation board? I see some in the data sheet, but these are for an older (or newer) revision than what I've got.

In particular, the single ended interface is gone, but the baluns are still there. Also, there's an undefined switch on the board, as well as two terminals (GND1 and ?...presumably Vadj) I'd like to know about.
